Tuna Nutrition Facts

The nutrition profile of tuna can vary slightly depending on the type of tuna as well as how it’s prepared. For example, there are more calories in canned tuna in oil compared to the amount of calories in canned tuna in water. Tuna steak nutrition also tends to be lower in sodium than canned tuna varieties.

So then what exactly is Subway's "tuna" made of? It doesn't seem to be what it claims to be

In a massive exposé spearheaded by The New York Times, a general study was done to find out if Subway's tuna is what the chain claims it to be — 100 percent real wild-caught fish.

The test concluded what many suspected: There was no trace of tuna DNA in Subway's "tuna."

According to the Times — which claims to have spent $500 on the independent tests — multiple PCR reports, which check specifically for DNA, found zero traces of actual tuna within the samples.

What is a tuna?

Tunas comprise fifteen species in the Thunnini family of saltwater fish. Of those, eight are considered “true tunas”: five species of bluefins and three species of yellowfins, all which belong to the genus Thunnus. (Skipjack, one of the most popular species of canned tuna, aren’t “true tunas.”)

Physiology and speed

Tunas are known for their sleek, torpedo-shaped bodies designed for speed and endurance. The Atlantic bluefin tuna, for example, can swim up to 43 miles per hour; the yellowfin can swim even faster. Tunas have crescent moon-shaped tails and two dorsal fins on their backs, one of which can be flattened to reduce resistance in the water.

Habitat and migration

Tunas are pelagic fish, meaning they live beyond the continental shelf in the open sea—not near coral reefs, the sea floor, or shoreline. The pelagic zone is the largest habitat on Earth, with a volume of 330 million cubic miles.

Tuna fishing and dolphin bycatch

Tuna has long been a staple of the diets of millions of people around the world and is considered to be one of the most commercially valuable fish. Skipjack tuna are the most-fished, by far, accounting for 50 to 60 percent of annual global tuna catches. Along with albacore (a type of bluefin), these species account for the majority of canned tuna.

Threats to conservation

One 2019 study found that the amount of tuna taken from the ocean has increased by 1,000 percent over the last 60 years —a rate that some scientists say is unsustainable.

Skipjack Tuna

Small in size, and dark in meat color, Skipjack Tuna are your most commonly canned Tunas. In fact, over 70% of the US canned Tuna market comes from Skipjacks. Their meat texture is tender, allowing for small chunks, perfect for canning.

Albacore Tuna

Albacore are the second most canned variety of Tuna in the US, taking up around 20% of the market. Often dubbed White Tuna, Albacores boast light flesh and a very mild flavor. They come in larger chunks in comparison to Skipjacks, and are generally a more pricey option.

Yellowfin Tuna

Pale pink and mild in flavor, Yellowfin Tuna are probably the most versatile Tuna food choice. You can find these fish in cans, as well as in the form of steak and sushi. In the US, Yellowfin is a popular sushi option for a couple of reasons.

Bigeye Tuna

Large and stout, Bigeye Tuna boast bright, firm meat, with loads of flavor. These fish are a great option for people who prefer fatty, flavorful fish, but don’t want to shell out a ton of money to get it. That’s not to say that Bigeye are cheap: a good piece of restaurant Bigeye sashimi can go for over $20.

Bluefin Tuna

Bluefins are widely regarded as the Kings of the Tuna family, and rightfully so. Thanks to a number of physical attributes, Bluefins boast a richness of flavor you just won’t find in another fish.

Different Types of Tuna: One for Every Occasion

Tunas are a fantastic source of nutrition, as well as an awesome tasting food option. Packed with protein and omega-3s, these fish should definitely be on your menu.

Be thankful for dolphin-free tuna

The video begins with an empty metal bowl. The Subway employee slips on a flimsy pair of plastic gloves and picks up a package of Subway's preferred tuna, flaked in brine. She makes careful note to point out that, according to the package, there were no dolphins harmed in the making of this package of tuna.

Mayo with a side of tuna

We have nothing against mayo. In fact, we love it. We love it on sandwiches, in potato salads, and mixed with herbs into a creamy dressing. Mayo is an undoubtedly important and versatile kitchen ingredient. The problem in the Subway employee's tuna video is not the presence of mayonnaise, it's the quantity of it.

You really don't want handmade tuna

But the real crime in Subway's tuna salad takes place after the mayo has been dumped into the bowl, when the employee proceeds to combine the mixture using — you guessed it — her hands.
